Hard to say. The drum-braked /5s have appreciated, but I haven't seen it in the later disk-braked models. In his 1990 Buyer's Guide for BMWs, Roland Slabon gives the /5s four stars, the R75/6 three stars (out of a possible five).
The /5 is a milestone, first of BMW's excellent plain-bearing engines and miles better than its competition. The /6 is a nice bike, but buy it to ride it, not as an investment.
A cosmetic restoration with some mechanical work could run $3000-5000; you would never recover that. What you might pay depends on what it needs. You should be able to find a decent one for around $2500.
There are not that many R75/6s around, because in 1974-76, everybody had to have the 900. I would rather run the smoother and more durable 750, however.
